Total : Spent : Left
10 : 3 : 10 - 3
10 : 3 : 7
710 of the remaining amount is the same as
59 of the total amount.
Amount that Adam has at first = 9 u
Amount that Adam spends on the marbles
= 28 u - 15 u
= 13 u
13 u = 260
1 u = 260 ÷ 13 = 20
Amount that Adam has at first
= 9 u
= 9 x 20
= $180
(b)
Amount that Adam spends on beads
= 15 u
= 15 x 20
= $300
Amount that Adam spends more on beads than on marbles
= 300 - 260
= $40
Answer(s): (a) $180; (b) $40
